453 GPS Important Update

Modification Details

PSA: Media-System in smart 453 is affected by the GPS Week Number Rollover bug.

You MUST Update before April 6th, 2019!

Hey folks!

On April 6th, 2019, GPS will experience aWeek Number Rollover. Basically, the GPS counts weeks starting
from Sunday 6 January 1980, and since it can only count up to 1024 weeks at a time, it reverts to 0 roughly
every 20 years. This already happened once in 1999, and will happen again this year.

What does this mean if you drive a smart 453 with a smart Media-System? Well, the bad news is that if
you don't do anything, your car will stop displaying the time or display it incorrectly, and if you use
the built-in TomTom navigation, it will display incorrect arrival times, among other potential issues.

The smart Media-System will restart, finish the update, and you're good to go! You can check that
the correct version was installed under Menu > System > Status & Information > Version information >
next to "Application". The correct version number should start with "11.344".

Android Auto Update

For those who followed my tutorial from last year toactivate Android Auto on a 2015/2016 smart 453,
and updated to version 11.343 in the process, you do still need to update to version 11.344 to
avoid the WNRO bug. However, I can confirm that Android Auto still works properly with 11.344.

Neelfyn is the guy who worked out the Android Auto update that I posted here and is now everywhere online.

He is the reason I looked at DDT4All and noticed other coding opportunities.
